To all whom it may concern.-

Be it known that I, LONGLEY LEWIS SA- GENDORPH, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State ofPennsylvania, have invented certain new and usefullmprovements inMetallic Ceiling-llates, of which the following is a specification,reference being had to the accompanying drawings, forming a partthereof.

The primary object of my invention is to construct or form the cornersof metallic ceiling plates, having raised marginal borders or moldings,in such a manner as to obviate the necessity of cutting away the metalat said corners, as is now commonly done.

In the drawingsz-Figure 1, is a plan view of a portion of a ceilingconstructed according to and embodying my invention, illustrating one ofmy improved plates in an operative position with corner rosettes inposition thereon. Fig. 2, is a plan View of one corner of the plateshown in Fig. 1. Fig. 3 is a View similar to Fig. 2, with an adjacentplate in position thereon; and, Fig. 4, is a.

sectional view on the dotted line l, 4, of Fig. 3.

In the accompanying drawings, A, represents one of my improved ceilingplates, having a continuous raised marginal border or molding a, saidmoldings extending beyond their point of intersection, as shown, formingthe projecting portions a at the corners of the plate. I also preferablyemploy an inner continuous raised bead or corrugation 1?, near themarginal raised portion a, in order to add strength and rigidity to theplate to prevent buckling of the latter.

In placing the plates to position on the ceiling, the projectingportions a will overlap the two marginal beads a on adjacent plates, asshown in Fig. 3, the corners thus formed being covered with rosettes D,each of which is provided with arms (1 of a circular outline incross-section, the latter fitting over the moldings a, and also over thetwo projections a on the top plate, as shown by dotted lines in Fig. 1.The rosettes are retained to place by a single nail driven through eachof them and through the overlapped portions of the moldings a, at theirintersecting points.

One of the prime advantages attained by my invention is, that theuniform rigidity afforded by the raised marginal bead or molding isretained, and the plate rendered. uniform throughout, which points ofadvantage are destroyed by cutting away the metal at the corners, as isnow commonly done. The corner projections a when the overlapping platesare secured together, have a tendency to strengthen the ceiling at thosepoints and where most needed; they also assist to prevent the platesfrom warping out of position when placed together on a ceiling, in themanner aforestated. The edge of each overlapping plate terminatesbetween the two two beads to and Z), and the latter, when decorated,have a tendency to detract the eye from said terminal edge, thusproducing a ceiling that is at once attractive and cheap of manufacture.

What I claim as new and desire to secure by Letters Patent, is:

1; A metallic plate having a raised margin or molding on each sidethereof, said moldiugs at the corners extending out beyond the margin ofthe plate, substantially as set forth.

2. A metallic plate having a continuous raised molding at around itsmargin, said moldings extending out beyond their intersecting points,substantially as specified.

3. A metallic plate having a continuous marginal moldinga, on each sidethereof, and an inner continuous raised bead 1) adjacent to saidmolding; the latter extending out beyond their points of intersection,forming projections a as and for the purposes set forth.

4:. A metallic ceiling composed of plates, each of which having a raisedmarginal molding a at each side thereof, said moldings extending outbeyond their intersecting points forming projections M, which latter areadapted to overlap a pprtion of the molding on adjacent plates, and asuitable rosette f each corner thus formed, substantially as set forth.

I rosette D having lateral arms (1 overlapping lo the corner moldingsand their projections (1 and properly secured thereto, substantiallyLONGLEY LEWIS SAGENDORIH.
